Industrial-Grade Electrical Terminal Lugs with Shear Bolt for Secure Cable Connections
The primary application of our shear bolt connectors is underground splices up to 35 kV. They are ideally suited for aluminum to aluminum, aluminum to copper and copper to copper applications making them the universal connector solution.
The Shear Bolt Connector's design incorporates shear head bolts, which shear off when the needed torque is applied to each bolt and consequently the optimal contact force is generated to minimize connection resistance.
The design of the connector had to be such that the installation is tool-free. Critical to quality always is consistency in connection, irrespective of installer skill. A platform technology of screw connector system was evolved.The shear head bolt so engineered, has the head of the screw bolt always shearing off when the designed torque is reached upon tightening the bolt over the conductor.
The Shear bolt Lug is designed to have one or multiple shear points based on the size of the connector. Serrations are made on the inside of the extruded alloy tube. The connector thus has firm point contacts with the conductor. Two paths of currents are created. One through the Shear bolt connectors and the second through these point contacts.
